I'll say this, Wireless Zero Config definitely isn't an option :)

It can be done. I've done it and at least one other person I know of has as

This is now autodetected, if I understand things correctly. You do not need
to modify this.

You need to uncomment PRISM2_DOWNLOAD_SUPPORT. I haven't been into this for
a few weeks now, and it appears the latest CVS has this uncommented by
PRISM2_NON_VOLATILE_DOWNLOAD is for cards that have flash memory to hold the
firmware. The DWL-520 rev. E1 does not, rather the firmware is downloaded
into RAM on system startup (in Windows).

That looks right.

I would do a google search. I think there are legal/copyright issues
surrounding the firmware, e.g. you have to own a card to download it from
the Internet. I'm not sure of the specifics. I have firmware files that
worked for me, if you like I will send you them.
The card has no permanent firmware on it, you can't download from there. You
are probably reading about either another card or an earlier revision of
